Police officers said they found Brandon Marchetti, 14, in a secured, fenced-in area of a construction yard being mauled by the two dogs.

Marchetti's friend, a 12-year-old boy, had called police, who fired at the dogs when they arrived.

The brother of the construction yard owner said it is believed the boys climbed a sand pile to get over the fence and into the yard.

Police say they had to use necessary force, so they shoot at both animals hitting one.

Revere police said one of their officers scaled the fence to rescue the teen, while Revere firefighters used water hoses to keep the dogs at bay, likely saving Marchetti's life.

Marchetti's parents said the boys frequently came to the area to play with the dogs and had permission to do so.

"It's not really the dog's fault, but I think they should have put them both down," said Brandon's father, Raymond Marchetti. "They literally ate my son. They tore his scalp off. We've been crying all night, to see our baby torn up."

Helen Soule manages a laundromat at the Northgate Mall adjacent to the yard. She says the guard dogs are scary.
